Thanks Bill and Terry. I have an NTE112 diode on order.
I have already performed the vacseal treatment on the CRT. It Seemed like an important thing to do.
The Tuner is all cleaned up and now I can tune a good picture looking with a scope at the input of the first video amp. Seems like maybe I will not have to touch the IF. I have not swept it yet. Next issue is that the color will not lock. I can get it to stabilize for a bit by turning the AFC balance control but then it will come unlocked again. Tweaking the AFC control again will bring it back to lock. The Hue control does seem to work but, looking at the scope, it looks like the hue is 180 degrees out, when it is locked. The reference oscillator appears to be working fine. I may not have much time this week to troubleshoot but I'll get back to it as time permits.
Once I get the cabinet out and the CRT installed, I'll post some photos. I am trying to get most of the troubleshooting and functional verification done before I put the chassis back in the cabinet.
